Fix `ImportError: cannot import name 'NoGdbProcessError'`

This release works for all operating systems, including Windows.

• Fix ImportError: cannot import name 'NoGdbProcessError' by pinning dependencies to ensure they are all compatible. Note that this means the only way gdbgui should be run is by installing inside a virtual environment, installing with pipx (as it uses virtual environments), or to run the executable build from gdbgui's release page.
